The sides of the hopper are slightly thickened at the center and are tapped at the bottom to receive set screws 12, extending through slots 13 in the top 7 of the main frame and provided at their lower ends with heads and ada ted to engage the lower face ofthesaid top 7 to clamp the hop )er in its adjustment. fThe hopper is adustable with respect to the feed rolls to enthe feed rolls a't the desired point along the same. a t

The flattened dough, which moves downwardly between the feed rolls 11, is caught between inner and outer transverse pressure or sheeting rolls 14 and 15 andis formed into a thin sheet through the squeezing and rolling action of the said rolls Hand 15, the outerpressure roll 15 being adjustably .moun-ted' tance between them and the consequent thickness .of the sheet intowh'ich the dough adjusted to' suit the character or condition ,of the dough operated on and also to cause the dough toybe subsequently wrapped or coiled into a spiral roll of as tight or loose in character as desired. The adjustable frame, w-hich is composed of spaced approximately L-shaped sides and connecting transverse bars or portions'l7and 18, is provided with'uppcr and lower bearing openings 19 and .20 through which-extend the terminal ,portions' of shafts 21 and 22 of theputer 'ressureroll and a forming roll 23. The

These plates also exclude flour dust and dough from the bearings and the gearing which rotates the rolls. The frame carrying the outer pressure roll is adjusted a nut 26, mounted for rotary movement in a pivoted block 27- of the adjustable frame 16 and engaging a screw 28, which is pivotally outwardly projecting arms 29 having threaded perforations for the reception of pivot screws 30, having heads at their outer ends and provided at their inner terminals with smooth portions, projecting i1 1ward-1y and arranged in bearing recesses 31 of the pivoted block 27. The block 27extends across the space and fits snugly between the arms 29, and it is provided with a central opening through which passes a tubular portion 33 of the-nut2G. The tubular; portion is provided with an exteriorly threaded portion 3a for the reception of a nut arranged in spaced relation with the head of the nut 26 and retaining the tubular portion 33 in the The screw 28, which is arranged at a slight inclination, is provided at its lower the ears. Any other suitable means, however, may beemployed for-pivotally mounting the screw on the main frame. The ad justing. nut has a swivel connection with the pivoted block and when rotated is adapt ed to raise or lower the outer portion of tin adjustable frame to rock the latter on the shaft 22 of the forming roll 23. The ad ustable frame also carries a scraper l0 considi g of a plate of metal or other suitable material a-nd'arranged in a slightly inclined position with its upper andlower edges co'ntiguous to the outer pressure roll 15 and the forming roll 23 "respectively to prevent the dough from adhering to the same The scraper is secured to the inner threaded terminals'41 of rods 42 adjustably mounted in perforations 43 of the transverse connecting bar17of'the adjustable frame 16. The scraper is preferably provided at its outer face withja transverse cleat or bar e l-secfired by screws or other suitable fastening connected with the main frame. The transverse connecting bar 18 of the adjustable frame is provided with spaced which is provided in its sideswith forming, roll 23, which has the inner portion of its periphery moving upwardly in the same direction as roll 47., j The forming roll portions of the rodsmeceive coiled springs 44 interposed between the transverse connecting bar 17 and. nuts 45 and adaptedto yieldably with the rolls 15 and 23. The nuts 45 engage outer threaded terminals 46 of the rods l2and are adapted to be adjusted to vary the tension of the coiled springs, and they are arranged in pairs to form 'a lock for retainingthem in their adjusted positions;

The sheet of dough after passing between the pressure rolls and before being released by the same is eiigaged by abottom forming roll 47, located below the ,pressure rolls and in spaced; relation with the-same and also below but'in close,proximity tothe forming roll 23, which, is considerably smaller than the bottom forming roll 47. The bottom formingroll 47, which rotates in .the direction of thearrow in Fig. 1 of'the drawings, catches the sheet of dough at the lower edge and carries the same into contact with the 23 curls or butfs'up the edge of the dough and coacts'; with the relatively large'forming I roll-47 'to,coil or wrap the sheet of dough intoa spiral roll, as"indicated in Fig. 1 of. the-drawings.

The trip plate 58, which is mounted in suitable guides 62 of the sides of the frame,.

is arranged at an inclination in substantial parallelism with the lower or lnner stretch of the trip belt, and it is provided at its upper edge with ears 63 connected by suitable pivots 64 to links 65 located at opposite sides of the pocket or. space 50 and pivoted in slots or bifurcations 66 of the sides of the adjustable frame by pins 67, or other justed. with the adjustment of the outer pressure roll. By this construction, the trip plate is moved upwardly and downwardly in the guides 62 by the adjustable frame as the outer pressure roll 15 is carried inwardly and outwardly, and-'itsposition is varied with the changing or ad ustment of the position of the said outer pressure roll 15. Only a relatively small amount of adjustmentof the trip plate 58, however, is necessary to adapt it to the varying condi tions of thev dough and to the various sizes of spirally coiled rolls thereof. The trip plate presents a smooth surface to the roll of dough and enables the same to be readily carried out of the pocket by the tripbelt,

:and it also operates to guide the roll in its downward passage from, the pocket 50 to f the conveyer 4:9. The guides 62, which are arranged at an inclination, are shown in thedrawin'gs asconsisting of spaced flanges projecting from the inner faces ofthe-sides of the frame,

The sections of the bottom 70 of the shaping or molding box are preferably connected at intervals by transverse cleats or bars 78, which support a longitudinally disposed chain guard 79, consisting of a' bar or strip vof metal arranged. in the bottom of the groove or channel 77 and suitably secured to the transverse cleats-7 8.

The upper portion 82 of the bottom of the box is smooth and the pressure onthe dough is decreased during the buflin'g of the ends andthe finishing of the shapingor molding of the loaf. I

The inclination of the endless conveyerand the opposite inclination of the trip plate form a lower pocket 83 into which the spiral roll of dough is deposited after itis tripped from the upper pocket.- The-lower; pocket- 83 serves to properly position .the roll of'dough and operates to start thesame" properly through themoldihg or shaping box, however,.o wing to thekneading surface 7 any irregularity in the position of the roll as it enters the. molding box will be taken care ofand a finished-loaf of the proper size and-shape will be produced, owing to the treatnfeht the dough receives intraveling over the undulatory kneading surface 81.
